Elegant in its simplicity and rooted in tradition, the Classic Kidney Copper Flask celebrates one of the earliest and most enduring designs from Jacob Bromwell®.
For more than two centuries, this iconic shape has remained virtually unchanged — refined through craftsmanship and discipline rather than redesign. Its curved kidney profile is thoughtfully designed to rest comfortably against the body, slipping easily into a front or back pocket while maintaining the reassuring weight and solidity of true heritage craftsmanship.
Expertly crafted from 22-gauge solid copper, each flask is finished using the brand’s signature SuperPolish™ process, producing a luminous, mirror-like surface that radiates warmth and timeless character. Inside, the flask is lined with molten, lead-free tin using a proprietary lost method, ensuring purity, durability, and generations of reliable use.
Designed for everyday carry yet built to last for decades, the Classic Kidney Flask embodies quiet confidence and enduring craftsmanship. It does not seek attention — it earns loyalty.
Imperfectly Perfect: Minor imperfections lend charm, depth, and individuality to each piece and are a natural part of the 100% handmade process. Each subtle mark reflects the authenticity of true craftsmanship. Embrace the imperfect — this is the Jacob Bromwell® way.
